Today's show is a best-of, so we won't be taking any calls. But the comments page is always open!
Brian Lehrer hosts the hosts, featuring interviews with Christiane Amanpour, Larry King, Tom Brokaw, and Jim Lehrer (no relation). First, a look back at the movements of 2011 from the Arab Spring to Occupy Wall Street and beyond with ABC and CNN's Amanpour, who this year interviewed Libya's Muammar Qaddafi and Egypt's Hosni Mubarak. Then, NBC's Tom Brokaw on "the greatest generation"; former CNN host King on asking "why" questions; and Jim Lehrer of PBS on moderating presidential debates.
